Letters Patent No. 96,818, dated November 16, 1869.

IMPROVEMENT IN MACHINE FOR CUTTING FELLOES.

'l'he Schedule referred to in these Letters Patent and making part ofthe same.

Be it known that we, WILLIAM A. LEWIS and GEORGE W'. BUTLER, of Joliet,in \Vil1 county, and State of Illinois, have invented a new and improvedMachinefor Cutting out Wagon-Felloes; and we do hereby declare thefollowing to be a full,k clear, and exact desclipt-iou of the same,reference being had to the annexed drawings, makinga part of thisspecification, in which.-

Figure l is a perspective View;

Figure 42, a plane view on the top;

Figure 3, a rear elevation ;v

Figure 4, a perspective view of a single cutting-bit; and

Figure 5, a view ou the bottom of said bit to show the curveof its outerside.

Thismachiue may be constructed wholly or in part of metal, as desired,and is operated and arranged as we shall now proceed to explain, relyingas much on the representations in the drawings as in the description, toconvey our ideas.

t is a frame, upon which rests an adjustable table in two separateparts, b and e, supported by the main frame a.

These parts may be moved' to or from each other by means of the counterscrew j, figs 2 and 3, which is boxed in the counter frame a, at eachend, and is attached t0 the two part-s of' the table?) and c, by meansofthe nut-boxes n and o, tig. 3.

It will be readily observed that by turning said screweach partof thetable will be moved either to or from the other, according to thedirection the screw is'turued, which is for the purpose of adjusting thedogs e and lto any distancevapart, to accommodate the machineto anylength of the pieceto be cut.

The set-screws s and slots prevent the tables from being moved too fareither way.

IThe adjustable table rests upon the frame t, which may be movedhorizontally, by means of the screw d, operating in the nut p, attachedto said frame, as shown in iig. 2.

.This is for the purpose of accommodating the dogs e and l to any circleto which the cutting-bits c may beset to cut.

The dog e is arranged 'to slide laterally, of the level' t', to receivethe block to be cut between them, as it rests upon the rests 8 and 9,shown in iig. 1.

fis au adjustable gauge, to regulate the distance the block is to beshoved into the machine between the dogs, so that the cut may be uniformeach time.

This gauge f is operated by the levers g and h, attached to the dog e,as shown iu, fig. 2, and is regulated by means of the slide q andset-screw r.

z is an upright shaft, standing ina step, 4,'on the elliptical spring l,upon which itis allowed to move pexpendicularly, by means of the levers2 and 3, the lever 2 having a forked end. which engages with said bymeans shaft, as shown in fig. 3, to bring it down, which is done bypressing down with the foot on the end-.of the lever 3, iig. 1.

The cutter-head m is attached tosaid shaft, as shown in ligs. 1 and 3,and revolves by means of a belt on the pulley 5.

A double row of concentric cutting-bits e are attached to saidcutter-head, and are arranged in radial slots, as shown in figs. 1 and2, by means of which they may be set to cut any desired circle, and mayalso be set at any distance apart, to cut any width of afelloe.

'lhe cutting-bits are constructed in about the shape shown in figs.4aud'5.

Fig. 4 is a perspcctiveview of, a single bit, which is constructed witha projectiouon the upper part, which lits into a correspoluling grooveon the under side of the cutter-head, shown at 6, figs. 1 and 3, theobject of which is to around while at work.

A cross-section of the cutting-bit is shown ati," i

prevent the bit from turning IVe are aware that machines have beenbefore used, iu` looks `quite sin'lilar, for the same purpose, butheilig objectionable, as compared with this, in several respects, themain ones of which are thata separate machine has had to-be used forevery different circle desired to be cut, while in this machine anycircle practicable vmay be cut, simply by adjusting the cutting-bits tosuit the circle.

Also, the cutting-bits are bl'ought down to their work, instead of thework being brought up to the bits, which is a great improvement, as canbe readily seen, as the table is-left perfectly solid and stationary, adesirable feature when we contemplate that the variation ofone-sixteenth of an inch will spoil the work for ielloes, whichisinvariably thc case when the table is moved up and down.

Claims.

fe claim- 1. The combination and arrangement of the shaft 2,.

o', and adjustable table baud c, as and for the purposes set forth.
